Re: [U-Boot-Users] Serial Console

buffers to find my problem. I can see console output being written to a buffer at IMMR|0x2811 (0xFA202881 in my case). The buffer pointer

That should be fine, once the data is written on that location, it's the responsibility for the serial output to read/clear the data. Normally he next data will arrive once that location is cleared, when the data should have been handled and when there is now serial data available.

the SMC services this buffer before the next call to smc_putc(...). I do not know. OR this may be one of the problems that I am looking for.

I don't know how your serial output is configured, but maybe the output is waiting for the ready signals that never arrive.
